The relative humidity is 100%, and the temperature is hot. In a few sentences, explain how the weather would change if the temperature drops and becomes cool.

d.all of the above are involved in the fertilization process.

Explanation:

During the fertilization process, haploid gametes fused to form a diploid cell called zygote. A diploid cell is a cell that contains two sets of chromosome.Gametes are haploid cells. During  sexual reproduction gametes ( sperm & egg) fuse  at fertilization to form a diploid zygote. The zygote develops into diploid organism. The two sperms simultaneously enters the egg to form embryo of triploid cells.The nucleus of the other sperm cells fuses with the two haploid polar nuclei in the centre of gametophyte. The resulting cell is triploid. This cell divides through mitosis and forms the endosperm a nutrient rich tissue inside the seed.
